Expansion header for socketing into a breadboard

For further detail, please refer to the QUTy-V01 schematic.

Development environment

Development for the QUTy is supported via PlatformIO. We recommend using the PlatformIO IDE for VSCode which is available for Windows, MacOS, and Linux.

Installation

Install the Git client on your system. For Windows users using an installer, the default installation options may be used.
Install Visual Studio Code.
Install the PlatformIO IDE extension for VSCode.
Install the QUTy platform:
```
 PlatformIO Home > Platforms > Advanced Installation > https://github.com/cab202/quty
```
If VSCode was running during the installation of git, you may need to restart VSCode first.
Create a PlatformIO project and configure the QUTy platform by creating a platformio.ini file:
```
 [env:QUTy]
 platform = quty
 board = QUTy
```
or, open an existing project in a workspace in VSCode:
```
 File > Open Folder
```
Ensure that platformio.ini is present in the root of the workspace by checking the file tree in the Explorer tab.

The PlatformIO IDE extension will automatically configure a project for the QUTy platform, when this file is present.
Communicating with the QUTy may require Silicon Labs CP210x Virtual COM Port (VCP) drivers to be installed on your system.

Examples

A number of example projects are available as part of the platform. These can be accessed via:

PlatformIO Home > Platforms > QUTy > Examples

quty_blinky_c
- 1 Hz LED flash, in C.
quty_blinky_asm
- 1 Hz LED flash, in Assembly.
quty_blinky_asm_bare
- 1 Hz LED flash, in Assembly (without startup code).
quty_serial_helloworld
- Serial monitor/stdio example (prints “Hello world!” on key press).
